Center speaker lacking volume output - Blu-ray Forum

Kuraudo · 03-22-2008, 10:17 PM

Ok so I have a

Infinity C250 (91db sensitivity)
and Boston Acoustics CR67 (89db sensitivity)
Theoretically if I lower the volume of the Infinity by -3db
on my PIONEER VSX-815 Receiver the volume should be the same.

I checked all the settings and set the Speaker to be LARGE as well and the wiring is correct in the back according to polarity and tightness in the back of the speaker and receiver.

However the volume is really low, it sounds several times lower than the LR channels. The sound quality on DTS ps3 games and movies sound kind of "tunnel like"

I bought my speaker off of ebay so how do now I'm worried if I got a "counterfeit speaker" but the build quality seems all very good and heavyweight.

Since the overall volume still is low, I have it at 0db.
At this level its still very low.

Any other input on this speaker and amp combo?
Everyone complains that they can't hear the movie unless I switch to stereo mode.

have you tried messing with the receiver's DSP modes? well, besides stereo that is.

1st... swap two speakers and see if it follows
2nd... how is your ps2 hooked up ? Optical ??multi, or red/white

Does this still happen if you leave the speaker levels as is after running MCACC?

If you have a subwoofer, set all the speakers to "small".
Why different brands of speakers? You could have a compatibility issue here.
Are all the speakers 8 ohms? If the center is 4 ohm, and the rest are 8 ohm, you will never get the volume from the center!

This will be corrected by running MCACC

Yes, precisely. I have MCACC on, and checked it on OFF (default settings)
no good still.

Setting speakers to small doesn't help matters in sound quality, since my speakers are full sized. Tried that, sounded ugly.

still need to know how you have the amp connected
did you try swapping speakers ??

Kuraudo · 03-26-2008, 04:29 AM

infinity is already mailing a replacement, but I have no idea if they are sending a replacement for both woofers

Kuraudo · 03-28-2008, 03:16 AM

Got my SINGLE woofer/driver in but not sure how to remove the 2 wires from the bad woofer , its clamped on. Do i yank it? Or do I need a tool? what kind of tool?

I listened carefully and I think the right speaker sounds worse than the left so I'm going to replace the right one.

(moved to correct thread)

Busy guys eh?

So I finally got out the clamp on the speaker wire..

A Use tiny screwdriver and press down into the slot and press and pull down at the same time.

So I guessed right and replaced the right woofer, its MUCH louder now
but the left woofer still sounds half dead and the center overall sounds mono. I knew the right one was much worse so its still better.
I'll call Infinity again and beg them for one more woofer, if not I'll pay. I put in the DTS eagles music cd and that sounds pretty nice now. This is the first time I have heard it sounding halfway decent.

Compared to the Bostons, the infinity sounds more colored and less natural but has a much more involving "in the action" affect. The driver isn't even burned in though so I can't speak too much of it. If the coloration in the bass is still existing after burn in, I'd say the Bostons are better and I would be thinking of buying a pair of boston CR67 and using just one as a center channel.

Any of you find that prologic II sounds really odd and out of phase sounding? By turning it on it drains the volume out of the left/right and center, rears sounding much less powerful than stereo.

Update again: Called infinity. Much busier on fridays!
They gave me no hassle about sending me another woofer for the left one.
They said no problem like instantly and did not ask rhyme or reason why!
I agreed to do their 3 question survey and praised the CSR as well.

Infinity rocks on for their customer service, it is quite rare!
No its not outsourced to India either

That's how all customer service should be. The process to actually getting around to sending my PC in for service took many days because the tech support (who almost always didn't speak English well or understand it when I spoke to them) had to test every little thing when I knew it was a hardware problem. *Sigh*
